Technical ContextAI · show details

This vulnerability is classified under CWE-378. The Java client for the Datadog API before version 1.0.0-beta.9 has a local information disclosure of sensitive information downloaded via the API using the API Client. The Datadog API is executed on a unix-like system with multiple users. The API is used to download a file containing sensitive information. This sensitive information is exposed locally to other users. This vulnerability exists in the API Client for version 1 and 2. The method prepareDownloadFilecreates creates a temporary file with the permissions bits of -rw-r--r-- on unix-like systems. On unix-like systems, the system temporary directory is shared between users. As such, the contents of the file downloaded via the downloadFileFromResponse method will be visible to all other users on the local system. Analysis of the finding determined that the affected code was unused, meaning that the exploitation likelihood is low. The unused code has been removed, effectively mitigating this issue. This issue has been patched in version 1.0.0-beta.9. As a workaround one may specify java.io.tmpdir when starting the JVM with the flag -Djava.io.tmpdir, specifying a path to a directory with drw------- permissions owned by dd-agent. Affected products include: Datadoghq Datadog-Api-Client-Java. Version information: version 1.0.0.
